About the Protein black outline icon
A wide band folds back on itself four times, forming a zigzag of flat tapering strands that reads as a protein ribbon or beta-sheet structure. It communicates amino acids, molecular biology and nutrition science, making it useful for supplement and sports nutrition labels, diet and fitness app screens, biochemistry lecture slides, lab and research websites, and health infographics.
The strands are drawn as outlined parallelograms of even width, tilting slightly so the folds stay distinct where they meet. The shape is broader than it is tall, which suits inline use beside text. Pair it with molecule, DNA and vitamin icons, and keep it at 32px or larger so the folds do not merge.
This is the black outline version of the protein icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
